title: [The morphological characteristics of hepatocyte dysplasia].
abstract: Two variants of dysplastic hepatocytes are revealed: small and large which are characterized by cell atypia and probably result from the disturbance of regenerative processes. The disturbance of the liver lobule architectonics is also a feature of dysplasia. The degree of hepatocyte dysplasia assessed by morphometric indices (nuclei surface, ratio of ellipticity) and its frequency increase with progression of the pathological process: chronic persistent hepatitis----chronic active hepatitis----liver cirrhosis----hepatocellular carcinoma. More frequent observation of the hepatocyte dysplasia in viral liver conditions (HBsAg in dysplastic hepatocytes) indicates the role of hepatitis B virus in the development of hepatocyte dysplasia. Increase of DNA content and nuclei polymorphism are observed in small and large dysplastic hepatocytes when the degree of dysplasia is increasing, this making these cells closer to cells of hepatocellular carcinoma and favouring the concept of hepatocellular carcinoma development in the foci of dysplastic hepatocytes, particularly in liver cirrhosis.
